Main Features
1) Anticorrosive:13 years in heavy industrial areas,50 years in the ocean,104 years in the suburbs and 30 years in cities.
2) Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
3) Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
4) Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
5) Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
6)Save time and energy:Galvanizing process is faster than other coating methods.
